Claims. 1

This invention relates to combination storm sash and screen structuresfor windows and pertains particularly to such assemblies as havepermanently fixed screens over a portion of the area thereof and apermanently fixed sheet of glass covering the remaining portion of theframe of the assembly. Such structure, also, have a slidable pane ofglass movable to and from a position covering the screened area of theframe, whereby a storm sash is produced for use in colder months and asa complete storm window for the opening being protected.

One of the important aims of this invention is to provide a combinationstorm sash and screen, the component parts whereof are constructed ofmetal created in ways capable of allowing quick assembly with a minimumamount of effort and tools.

A further aim of the instant invention is the provision of a framestructure for combination storm sash and screens, which frame structurehas unique parts for securing a sheet of glass in place through theemployment of metal units only and without the use of caulking compoundsor putty that might become hardened and inefiicient after a period ofuse.

A yet further aim of this invention is to provide a unique frame elementfor combination storm sash and screen, which frame element is composedof a pair of interlocked strips each contoured to present functionalgrooves, one for the reception of a retaining clip for the permanentsheet of glass and the other contoured and disposed to receive theslidable section of the storm window when the structure is in place.

Details Of construction constitute important objects of this invention,and such aims and the character of forming and using the novel componentparts constituting the invention will appear during the course of thefollowing specification, referring to the accompanying drawings,wherein:

Fig. 1 is a condensed front elevational view of the combination stormsash and screen structure made in accordance with my invention.

Fig. 2 is sectional view taken on line 11-11 of Fig. 1, looking in thedirection of the arrows.

Fig. 3 is an irregular cross sectional view taken on line ZIP-III ofFig. 1, looking in the direction of the arrows.

Fig. 4 is a fragmentary, perspective, stretch-out view of one corner ofthe frame forming a part of the structure and illustrating the manner ofpplying the splicer thereto.

Cir

Fig. 5 is a fragmentary, perspective, stretch-out view illustrating themanner of interlocking the two component formed strips constituting themain frame of the structure.

Fig. 6 is an enlarged, fragmentary, cross sectional view through one ofthe rails of the frame; and, 1

Fig. 7 is an enlarged, perspective view of one end of the muntin barentirely removed from the remaining portions of the structure.

The form of storm sash and screen structure chosen for illustration isadapted particularly for application to the window frame of a building,which window frame is broadly designated by the numeral i9 and includesa conventional sill l2 at the bottom of the frame and adjacent to thestop 1 4 which extends around the opening formed by the frame. The frameper se comprises a pair of end rails I 6 and I 8, respectively, normallydisposed at the upper and lower portions of the structure and windowframe It), and a pair of identical side rails 29 that join rails is andIt to complete a frame having a size comparable to the opening withinthe window frame 10 and capahle of being attached thereto through themedium of conventional hangers 22 fastened to the upper rail 16.

When the frame is assembled, the upper and side rails t5 and 29,respectively, present outturned flanges 29 that lie in the major planeof the frame and rest against the outer surface of window frame I9across the top and along the two opposite vertical sides thereof. Thebottom rail i8 is spaced slightly above sill i2 as shown in Fig. 2; and,in the event rain passes through the hereinafter-described screen, itwill be carried away along the upper, downwardly and outwardly inclinedsurface l2 of the sill.

A V-shaped weather stripping 26 is secured to the outer faces of railsl6 and 29, respectively, in a manner clearly shown in Figs. 2 and 6;and, when the frame is in place, this weather stripping will be confinedin a compressed condition between the outer edge of rails l6 and 29 andthe inner face of the window frame it. One leg 28 of weather stripping26 is secured to the rails of the frame, and the other leg 39 of weatherstripping 2-6 is free to flex to the position and condition shown inFig. 2.

In practice, this weather stripping 26 is composed of rubber andcooperates with outturned flanges 24 in sealing the meeting surfaces ofthe.

sash and window frames against passage of the elements into the buildingupon which the structure made according to my invention is mounted.

The upper and side rails l6 and 20, respectively,

cooperate in forming a groove 32 along the top and two vertical sides ofthe structure, and this groove 32 receives a movable sheet of glass 34which is mounted in a metal binding 36. The manner of forming thisbinding 36 and securing the same to the marginal edges of the sheet ofglass 34 is clearly shown in Fig. 2.

When the binding is mounted in the opposed grooves 32 of the verticalside rails 29, this shiftable sheet of glass v34'may assume the positionshown in Fig. '2 to cooperate with another sheet of glass 38 in forminga full-length storm window; or the sheet of glass 34 may be movedupwardly in the direction of the arrow shown in Fig. 2 to a position inparallelism with sheet of glass 38 to permit screen to function ina'no'rmal manner during the time when the user of the structure isdesirous of admitting air through the window frame of the building andby way of screening or foraminousmaterial 40.

The combination storm sash and screen frame composed as above defined isdivided into two substantially equal areas, one of which is permanentlycovered by screen 40 while the other area is permanently covered bysheet of glass 38. The means for dividing the said structure is in thenature of a double muntin bar 42 having outwardly-directed grooves 44and 46, respectively, to receive a securing strip 48 and a retainer 50for the screen and sheet of glass 40 and 38, respectively.

Therecuring strip 48 is frictionally held within groove 44 formed inmuntin bar 42 and in a similar groove 52 formed in rail 18 across thebottom of the assembly. Each side rail 20 has a groove 54 providedtherein to receive another stretch of securing strip 48. Thus, as shownin Fig. 1, screen 40 is held in place by four separate, U-shapedsecuring strips 48 extending around the opening between the bottom railI8, muntin bar 42 and the lower portions of side rails 20.

The sheet of glass 38 is held in position by retainers 56 along twoopposite edges thereof, and retainers 58 engage the sheet of glass 38along the remaining two opposite edges, as shown in Fig. 1. Theseretainers are U-shaped in transverse oross section, and one leg 60thereof is shorter than the opposite or remaining leg 62 for the specialpurpose of affording an interlocking element and a facing strip acrossthe marginal edge of sheet of glass 38.

The side retainers 58 have the bights 64 and the relatively wide legs 66thereof extended beyond the ends of double muntin bar 42 to cover thezone of juncture or the end of muntin bar, as clearly illustrated inFig. 1. In this respect, screw 68 extending through opening 10 in aportion of muntin bar 42 is housed within the groove 12 of side rails20.

The L-shaped finger 14 at the end of muntin bar 42 is formed as shown inFig. 7; and, when screw 68 is .placed as more graphically shown in Fig."3, the muntin bar will be held in place and the screw head 68 will behoused within groove 12 which is closed by the overhanging portion ofretamer-58.

Each-retainer 56 and 58, respectively, which secures sheet of glass 38in place, has the relatively short leg 60 and 76, respectively, thereofconfined within the grooves and behind a shoulder 18. Thus, when theretainers are in the position shown in dotted lines in Fig. 6 and, also,in Figs. 1,2 and 3, the same will be held against accidental outwardmovement and against the sheet of glass. 38.

The main frame of the entire assembly comsurfaces I2 thereof.

prises four separate parts as above indicated, 1. e., the end rails l6and I8, respectively, and side rails 20. These rails are hollow andpresent a chamber 80 into which the L-shaped splicer 82 is fitted whenthe parts are assembled. One splicer at each corner of the main frametightly engages the proximal portions of the rails l8 and 26 or !6 and26, as the case may be; and, while these splicers tightly andfrictionally grip the said rails, it has been found desirable, in someinstances, to employ a desired number of fastening screws 84 passingthrough a desired part of the side rail and the splicer 82.

The normally upper end rails l6 and side rails 26 are formed of twostrips of material contoured as shown in Fig. 5 and interlocked alongtheir longitudinal, marginal edges as becomes evident by an observationof the parts illustrated in Figs. 5 and 6 in the order mentioned. Thenormally inner strip 88 is bent as indicated in Figs. 5 and 6, as wellas on a smaller scale in Figs. 2 and 3; and it is this strip 85 whichforms groove 32 for the reception of the reciprocable sheet of glass 34.

This groove 32 is continuous along the side rails 25 and across the endrail IS. The other strip 86 forms groove 46 wherein the glass and screenretainers 5-5 and 54, respectively, are confined. In the case of the endrails 16, the retainer 56 is mounted in the groove 46 with the innerrelatively short leg of the retainers held behind the shoul- .ers 7B.

The length of legs 60 of the retainers 56 and 58, as the case may be, issubstantially the same as the width of the groove entered by theretainers; and the inherent resiliency of the strips 88 from which therails are made permits introducing the retainer 55, for example (Fig.6), in the manner shown.

The rebent marginal edge 90 of strip 88 embraces one longitudinalmarginal edge of strip 86 to form the flange 24 heretofore defined asbearing against the outer surface of the building around the windowopening with which the structure is employed. 'The rebent marginal edge92 embraces the opposite longitudinal marginal edge of strip 88 to formgroove 46 and the retaining shoulder 18. These strips 86 and 88 areindividually created and then moved into assembled condition as shown inFig. 5. A stiffened, rigid rail is thereby produced.

Normally lowermost end rail I8 is devoid of this flange 24, for thisrail lies above the sill of the window and in slightly spacedrelationship to the downwardly and outwardly inclined upper In the eventrain enters screen 49 and drops down behind this lower rail i8, the rainwater will escape by running along the inclined surface l2 below railIt. When the structure is employed as a complete storm sash with thesheet of glass 34 in the lowered condition as shown in Fig. 2 andcovering the screened area, a weather strip 94 along the bottom ofbinding 36 will rest upon sill surface l2 and cooperate with the weatherstripping 26 around the remaining three sides of the structure inpreventing the ingress of the elements.

When the structure is assembled, normally lower end rail I 8 and twoside rails 20 are secured together at their corners by the splicers B2and the double muntin bar 42 is placed through the medium of screws 68.Screen 40 is moved to position and its marginal edges forced into thegrooves 52, 44 and T2 of normally lower rail [8, muntin bar 42 and siderails 20, respectively, by securing strips 48.

Retainer 56 is then moved intogroove 46 of muntin bar 32 and the sheetof glass 38 slipped between the leg 62 of retainer 56 and the edge ofmuntin bar 42 that is in opposed, spaced relation with legs 32 as seenin Fig. 2. Retainers 58 are then slipped into position along theopposite normally vertical edges of the sheets of glass 38 with theextended ends overlying the ends of muntin bar 42 as hereinbefore setdown.

Normally upper rail I6 is then moved to position with retainer 56 in itsoperative position within groove 46. Splicers 82 have one stretchthereof within rail I6; and, when the other stretches of the splicersare forced into chamhers 80 of side rails 20, the said normally upperrail i6 is secured in place to complete the assembly of the entirestructure. With the sheet of glass 38 thus held in position around allof its marginal edges by the retainers which have their relatively shortlegs 60 interlocked behind the shoulders 18, aid sheet of glass 38 willnot accidentally move from operative position, and a tight, rigidarrangement of parts is accomplished.

Double muntin bar 42 is formed from two strips of material contoured tohave the marginal, longitudinal edges in overlapping relation as shownin Fig. 7, thus, also, to create a shoulder 18 in the groove 46 and withwhich the retainer 56 will cooperate.

Having thus described my invention, what I claim as new and desire tosecured by Letters Patent is:
